TREE AND LOG SAWING MACHINE.

SPECIFICATION forming art of Letters P Application filed February 20, 1885.

T 0 all whom it may concern.-

Be it known that I, WILLIAM E. HILL, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Tree and Log Sawing Machine, of which the following is a specification.

This invention has for its object an im proved machine for felling trees and cutting up logs.

The principal features of the invention are an engine pivotally supported in a manner to tilt vertically, and swiveled to swing laterally, a saw connecting with the free end of the piston-rod, and a guide-support to the saw connecting with the engine in a manner to tilt with it and the saw, all of which are more particularly described in connection with further details below.

In the drawings forming a part of this specification, Figure 1 is a side view of the machine in the position it occupies when felling trees; Fig. 2, the same, showing a change in position, as when sawing up logs; Fig. 3, a de tail in Fig. 1 (marked F) enlarged, hereinafter described; Fig. 4, broken parts of Fig. 1, en larged portions being in horizontal section; Figs. 5 and 7 enlarged details of Fig. 1 (marked f c) in perspective. Fig. 6 is a view looking against the 1eft-hand end of the engine, enlarged; Fig. 8, a side elevation of Fig. 9, and Fig. 9 is a top view of the engine-support in Figs. 1 and 2. 7

Referring to the letters of the drawings, P is the engine pivotally supported in a horizontal position in the bearing-support L. This bearing-support is provided with journal-boxes to contain the axial lugs on each side of the engine, thus pivoting the engine in a manner to tilt vertically. The bearing support L is swiveled in the base-support X in a manner to allow the engine to swing in either lateral direction around said point of swiveling. The base-support X may be supported by pivotally-connecting legs, or may rest on a skid used for moving it from one location to another. The legs here shown consist of parts a, hollow, and parts a passed therein and adapted to slide in or out for adjusting the height. The saw D connects with the free end of the piston-rod. The saw is provided with a guide-block, d, at the point of connection atent No. 329,554, dated November 3, 1885.

with the piston-rod. Swiveled to the end of the engine-cylinder is a collar, f, held at different rotated positions by set-screw S. This collar has two side bars, a c, secured thereto, which extend out horizontally parallel with the saw, where they are connected by a plate which is slotted to straddle the saw.

0 is a brace and an aligning rod connecting with the collar and end plate. The guideblock d is grooved at the sides and plays upon the side bars, 0 a. By turning the nut on the end of the combined brace and aligningrod 0, above referred to, the desired alignment of the side bars, 0 c, with the sliding block at may be effected. Anchor-rods a a are jointedly connected with the base-support X, each side of the engine I in a manner to be thrown down, as in Fig. l, to connect with each side of the stump when felling a tree, or to be thrown up to connect with the log when in a horizontal position in the operation of sawing the log up into blocks, as in Fig. 2. The free ends of the anchor-rods are provided with a sharp right-angled point for driving into the log or tree B B.

In Fig. 4, I shows the piston in the cylinderengine 1, and T is the piston-rod, to which the saw D in Figs. 1 and 2 is connected. R is the steam-chest, and t a flexible inductionpipe, which admits of swinging or tilting the engine to different positions. As the construction of this class of engines is well understood, no further description of details is here needed.

In Fig. 3 a rest, F, is shown for supporting the saw D,when starting it in the tree B. This rest may not always be needed. It consists of a casting of U form, with a vertical extension connecting one of the free ends,and provided with spurs y y, for driving into the stump to hold the rest. Gage-bolts a n are inserted in each side of the U portion and adjustably extended into the opening in which the saw D plays, forming a space between the inner ends of said bolts for the saw to play freely without danger of wabbling.

In the operation of felling trees the saw D, piston-rod T, the saw-support c, c c, and d, and the collar f are turned (the collar f being swiveled, as before stated, Fig. 4, and the piston being free to turn in the cylinder, admitting of said action) as in Fig. 1, so that the saw is in a horizontally-flatwise position. tails of the mechanical construction of parts When sawing up alog, 13, these parts are are illustrated, which will be readily underturned so as to bring the saw in a verticallystood, and which are suggestive of a possible edgewise position with the teeth downward, way of making the machine without further 5 as in Fig. 2.
